How many grams of Ca(OH)2are required to make 1.5 L of a 0.81 M solution?
FrozenT [24]

Answer:

Mass = 90.28 g

Explanation:

Given data:

Mass of Ca(OH)₂ = ?

Volume of solution= 1.5 L

Molarity of solution = 0.81 M

Solution:

First of all we will calculate number of moles.

Molarity = number of moles / volume in L

by putting values,

0.81 M = Number of moles / 1.5 L

Number of moles = 0.81 M × 1.5 L

Number of moles = 1.22 mol

Mass of Ca(OH)₂ in gram:

Mass = number of moles × molar mass

Mass = 1.22 mol × 74.09 g/mol

Mass = 90.28 g

How many liters of carbon dioxide will 0.5 mole of lithium hydroxide (LiOH) absorb? (One mole of any gas occupies 22.4 L under c
Svet_ta [14]

Answer:

0.5 moles of LiOH will absorb 5.6 L of CO_2

Explanation:

According to law of conservation of mass, the sum of mass on the reactant side must be equal to the sum of mass on product side.

The balanced chemical equation is:

2LiOH+CO_2\rightarrow Li_2CO_3+H_2O

2 moles of LiOH absorb 1 mole of CO_2 i.e. 22.4 Liters at STP

0.5 moles of LiOH absorb

=\frac{22.4}{2}\times {0.5}=5.6Liters

0.5 moles of LiOH will absorb 5.6 L of CO_2
