Question

6,0x10^23 moléculas de água-----------------1 mol
12,0x10^23 moléculas de água------------------x
x = 12,0x10^23/6,0x10^23 = ???? mol de H2O

Answer 1

Resposta:

x=2 mols

Explicação:

6,0x10^23----------------- 1 mol

12,0x10^23---------------- x

x = (12x10^23)/(6,0x10^23 )

x= 12/6 .(10)²³-²³

x= 2 .(1) = 2 mols de H20
