Araindrop has a mass of 50. mg and the pacific ocean has a mass of 7.08 x 10^20 kg. use this information to answer the questions below. be sure your answers have the correct number of significant digits. what is the mass of 1 mole of raindrops? round your answer to 2 significant digits. how many moles of raindrops are in the pacific ocean? round your answer to 2 significant digits.

Explanation: It is known that according to mole concept, 1 mole of every substance contains atoms. Therefore, mass of 1 mole of raindrops is as follows. Mass of 1 mole raindrops = mass of 1 rain drop × Avogadro’s number = = mg or, = (as 1 mg = 0.001 g) Therefore, mass of 1 mole of raindrops is g. Now, the mass of Pacific ocean is calculated as follows. Mass of Pacific ocean = As 1 kg = 1000 g. So, mass of Pacific ocean will be equal to . Hence, moles of raindrops will be calculated as follows. Mass of Pacific ocean = = = 24 moles Therefore, we can conclude that 24 moles of raindrops are in the Pacific Ocean.

a. 1 mole of raindrops weights 18 g b. 5,4×10²¹ moles of raindrops are in Pacific Ocean Explanation: a. Chemical composition of raindrops is water that is composed by two hydrogen (One hydrogen mole weights 1 g) and one oxygen (One oxygen mole weights 16 g). Thus, one water mole weights: 16 g + 1 g + 1 g = 18 g b. 96,5 % of Pacific Ocean is water (Raindrops). So, the mass of raindrops in Pacific Ocean is: 1×10²⁰ kg × 96,5% = 9,65×10¹⁹ kg of raindrops With the molar mass of raindrops (18 g/ 1 mol) it is possible to know the moles of raindrops in the Pacific Ocean, thus: 9,65×10¹⁹ kg of raindrops × (1000 g / 1 kg) × ( 1 mol of raindrops / 18 g) = kg to g g to moles 5,4×10²¹ moles of raindrops in the Pacific Ocean I hope it helps!

Explanation: a) 1 mole = particles/atoms/ molecules Mass of a rain drop = 50 mg Mass of rain drops: Mass of 1 mole of rain drop = b) Mass of pacific ocean = M = 1 kg = 1,000,000 mg Mass of 1 mole of rain drop = Let the number moles rain drops in the pacific ocean be x. 23.6 ≈ 24 There are 24 moles of rain drops in the pacific ocean.

im pretty sure it’s 24 Explanation:

Raindrops vary in size from about 0.02 in. (0.5 mm) to as much as 0.33 in. (8 mm) in thunderstorms. Raindrops come in many different sizes and can get to as big as a quarter inch. They cannot get bigger than that and the reason is that the wind resistance begins breaking them up into smaller raindrops. Raindrops don’t get much larger than a quarter inch

Answer 6

Solution: According to the Avogadro’s number: 6.022 *10^23 drops per 0.050 g/ drop = 3.011 *10^22 grams per mole of drops 3.011 *10^22 grams per 1 kg / 1000 grams = 3.011 *10^19 kilograms / mole of drops thus the answers are: 3.0 *10^22 grams per mole of drops 3.0 *10^19 kilograms per mole of drops And,

In the calculation of how many moles of raindrops in the Pacific Ocean is: 7.08X10^20kg per 3.0 *10^19 kilograms per mole of drops = 23.5 moles of drops

This is the required solution.
