Answer:

This chemical reaction is a combustion.

n = 1.8mol

Explanation:

The ratio of oxygen to water is 13 to 10

The ratio of oxygen to water is also 43 grams to x

Cross multiply: 13x = 430 grams

Isolate x: x = 33.0769g

Remember that n = mass/Molar mass

The molar mass of water is 18.01528 g/mol

n = 33.0769/18.01528

n = 1.836048
