How many moles of oxygen are represent in 0.16 g of oxygen gas?

Answer 1

using the equation moles=mass/molar mass

(since its in gas form) O2 => 16*2 =32

0.16/32=0.005 moles :)

Answer 2

To find the number of moles of oxygen in 0.16 g of oxygen gas, you first need to determine the molar mass of oxygen (O2), which is about 32 g/mol. Then, you can use the formula moles = mass / molar mass to calculate the number of moles. In this case, 0.16 g / 32 g/mol = 0.005 moles of oxygen gas.
