## How many grams are in 9.0 moles of aluminum?

The molar mass of aluminium is 27 grams per mole. Therefore, 1 mole of aluminium will weigh 27 grams. Thus, the total number of moles in 9 grams of aluminium = **9g/27g**.

## How many atoms are in 9 grams of aluminium?

No. Of atoms of Al in 9 gram = 0.333× Avogadro no. =0.333×6.022×10^23=**2.005×10^23 atoms**.

## What is the mass of 5.2 moles of aluminum?

Selina – Chemistry – Class 7

then, 5 moles of Aluminum (Al) = 5×27 = **135 grams**…

## How many grams of aluminum are in 4 moles of aluminum?

Thus,the mass of 4 moles of aluminum atoms is **108 grams**…..

## Is a mole equal to a gram?

Thus, for example, one mole of water (H_{2}O) contains 6.02214076×10^{23} molecules, whose total mass is about **18.015 grams** and the mean mass of one molecule of water is about 18.015 daltons, roughly a combined atomic mass number of 18.

## How many moles are in aluminum foil?

Next, you must convert the mass of the sample to moles by using the molar mass of aluminium, which is equal to 26.982 g mol−1 . Finally, to convert the number of moles to atoms, use the fact that **1 mole** of aluminium must contain 6.022⋅1023 atoms of aluminium → this is known as Avogadro’s constant.

## How many atoms are in 9 grams of aluminium and 0.8 grams of iron?

Explanation: of moles of atoms present in 9 grams of aluminium is 0.33 moles. mole of a substance contains 6.022×10 atoms/molecules so 0.014324 moles will contain 0.014324×6.022×10 atoms. i.e 0.086259×10 atoms of iron which is approximately equal to **86.259×10 atoms**.

## How many moles are there in 0.9 gram water?

=**3.01×1022 molecules**.
