Question

The molar mass of oxygen(O2) is 32g. what is the mass of 1.05*10^25 molecules of O2

Answer 1

3.36×10²⁶ g

Step-by-step explanation:

Molar mass ( O2) = 32g/mol

mole(O2) = 1.05×10²⁵mol

Mass(O2) = ?

mole(n)= mass(m)/Molar mass(M)

n×M = m

1.05×10²⁵ mol × 32g/mol = mass

mass= 3.36×10²⁶ g
