0.2 moles of aluminum has a mass of 5.4 g. what is The molar mass of aluminum

Molar mass = 27 g/mol

Explanation:

Given data;

Number of moles of Al = 0.2 mol

Mass of Al = 5.4 g

Molar mass of Al = ?

Solution:

Formula:

Number of moles = mass/molar mass

By putting values,

0.2 mol = 5.4 g/ molar mass

Molar mass = 5.4 g/ 0.2 mol

Molar mass = 27 g/mol

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

the product of the pressure and volume is also constant
