The initial 10.0 grams of water is a kind of intensive property.

What do you mean by intensive properties?

Intensive properties are those properties which do not depend upon the amount of the given substance. For example Temperature and pressure.

Generally, grams are used to represent concentrations. Therefore, always consider extensive. However, in the given question, the concentration is specified i.e. means fixed. So, the 10.0 grams of water become intensive in the given conditions.

Hence, the answer is an intensive property.

0.378g grams of a compound is made up of 0.273g of Mg and 0.105g nitrogen. Find its empirical formula.
Harrizon [31]

Answer:

The empirical formula of the compound is Mg_3N_2.

Explanation:

Mass of magnesium in compound = 0.273 g

Mass of nitrogen in the compound = 0.105 g

Moles of magnesium =\frac{0.273 g}{24.305 g/mol}=0.0112 mol

Moles of nitrogen = \frac{0.105 g}{14.0067 g/mol}=0.00750 mol

Form empirical formula divides the lowest value of moles of an element present with all the moles of elements present.

Magnesium =\frac{0.0112 mol}{0.00750 mol}=1.5

Nitrogen =\frac{0.00750mol}{0.00750 mol}=1

The empirical formula of a compound:

Mg_{1.5}N_1=Mg_{\frac{15}{10}}N_1=Mg_{15}N_{10}=Mg_3N_2

The empirical formula of the compound is Mg_3N_2.
