How many grams are in 4 moles of Li2O?

How many grams are in a mole of Li2O?

13.8 g/mol + 16.0 g/mol therefore the molar mass of Lithium oxide is 29.8 g/mol.

How many grams are in 4.900 moles of Li2O?

Multiplying this molecular mass by the given number of moles will give the weight in grams of the substance. Therefore $4.500$ moles $L{i_2}O = 29.881g/mol times 4.500moles = 134.46grams$.

How much is 4 moles O2?

Since 1 mole of oxygen is equivalent to 32 g, 4 moles of oxygen gas would be equivalent to 4 moles x 32 g/mole = 128 g. Thus, 4 moles of oxygen gas (O2) would have a mass of 128 g.

How many grams are in 4.50 moles of lithium oxide li2o?

So to get the mass of 4.500 mol , we simply mulitply the molar mass by the number of moles: 29.88 g⋅mol−1 × 4.500 mol ≈ 130⋅g .

How many molecules are in 23 moles?

The number of molecules of oxygen in 23 moles of oxygen is 1.385 x 1025 molecules of oxygen.

How many moles is 25 grams of water?

Hence, 1.38 moles (mol) are present in 25 grams of water.

How many oxygen molecules are in 32 moles?

One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.
