## What is the mass of 10.0 mole of water?

Number of moles=Mass/Molecular Mass. n=m/M. 10=m/18. Therefore,Mass of 10 moles of water =10×18=**180 g**.

## What is the mass of 4 moles of Aluminium atoms?

Mass of 4 moles of aluminium atoms = (27 x 4) = **108 g**.

## How do you convert 12g of oxygen gas to moles?

Here we are given the mass of oxygen gas as 12 grams. Molar mass = 2×16 = 32 grams. We know the formula to calculate the number of moles. = **0.375 moles**.

## What is the mass g of 1.250 moles of sodium?

The molar mass for NaCl is 58.44 g/mol. Converting 1.250 mol NaCl to grams provides **73.05 g** NaCl: 1.250 mol NaCl×58.44 g NaCl1 mol=73.05 g NaCl.

## What is the mass of 5 moles of sodium?

Mass of sodium is 23 grams. So the total mass of 5 moles of sodium will be 5×23=**165** .

## What is the mass of 0.5 mole of n2 gas?

mass of one mole of nitrogen gas is 28 gram(14*2) mass of 0.5 mole of nitrogen is **14 grams**.
