What is the percentage of oxygen in Li(NO2)3
BartSMP [9]

Answer:

66.2 % of O

Explanation:

Our compound is the lithium nitrite.

LiNO₂

This salt is ionic and can be dissociated: LiNO₂ →  Li⁺ + NO₂⁻

We determine the molar mass:

molar mass of Li + 3 . molar mass of N + 6 . molar mass of O

6.94 g/mol + 3. 14 g/mol + 6 . 16 g/mol = 144.94 g/mol

The mass of oxygen contained in 1 mol of lithium nitrite is:

6 . 16 g/mol = 96 g

So the percentage of oxygen present is:

(96 g / 144.94 g) . 100 = 66.2 %

dimulka [17.4K]

Answer:

The answer is: 7.7\times10^{10}

Explanation:

Scientific notation is of the kind: a.bc\times10^{x}

The given calculation:

7.0\times10^{3}\times1.1\times10^{7}=(7\times1.1)\times10^{(3+7)}

=7.7\times10^{10}

Therefore, the answer in scientific notation is: 7.7\times10^{10}
