## What is the mass in grams of 2 mole of lithium?

Based on the chemical formula, we have 2 atoms of Li, so the atomic weight of Li has to be multiplied by 2 to obtain 13.88 g/mol.

## What is the mass in grams of 1 mole of lithium?

Lithium for instance has an atomic mass of 6.941 grams and this is equal to one mole of lithium.

## How many grams of lithium are in 2.2 moles of lithium?

There are 2.2 moles of Li in 15 grams of Li. To convert between grams and moles, molar mass must be used. Molar mass for an element is found on the periodic table and is numerically the same value as the atomic mass. The atomic mass for lithium is 6.94 amu while the molar mass of lithium is 6.94 g/mol.

## What is the mass of 3 moles of lithium?

Answer and Explanation: The mass in 3 moles of LiOH = 72 grams.

## How many grams are in a mole of Li2O?

Li2O is composed of Lithium and Oxygen atoms. If you refer to your periodic table, the atomic weight is the molar mass of each element. The molar mass of Lithium is 6.9 g/mol and Oxygen 16.0 g/mol. the molar mass of lithium Li2O is 6.9 × 2 = 13.8 g/mol.

## How many grams are in 4.5 moles of NaF?

Answer. Explanation: mass of sodium is 23 and mass of fluorine is 19 there mass of NaF is 42. 42g =1 mole therefore 4.5 moles will have 4.5into 42 = 189g.
