Answer:

For one atom of lithium -6 I will need_16.85____ atom of lithium -7 for an average atomic mass of 6.944 .

Explanation:

1 ) Let required atom be m .

\frac{6\times 1 + 7\times m}{1 + m} = 6.944

6 + 7m = 6.944 + 6.944m

7 m - 6.944 m = .944

.056 m = .944

m = 16.85

An oxide of trivalent metal contains 32% of oxygen. Calculate the atomic mass of the metal.​
jekas [21]

The atomic mass of the metal.(M) = 51 g/mol

<h3>Further explanation</h3>

Given

32% of oxygen

Required

the atomic mass of the metal.​

Solution

An oxide of trivalent metal : M₂O₃(Ar O = 16 g/mol)

The molar mass of metal oxide = 2M+16.3=2M+48

32% of oxygen, then :

32% x 2M+48 = 48

0.32(2M+48)=48

0.64M+15.36=48

0.64M=32.64

M=51
