Molarity can be defined as the number of moles of substance dissolved in 1 L of solution.
In the given question ,
number of LiOH moles - 1.495 mol
Dissolved volume - 750 mL
molarity is calculated for 1 L = 1000 mL
In 750 mL - 1.495 mol of LiOH is dissolved
Therefore in 1000 mL - 1.495 mol / 750 mL x 1000 = 1.99 mol

List two reasons why atmospheric pressure changes ​
Dahasolnce [82]
This change in pressure is caused by changes in air density, and air density is related to temperature. Warm air is less dense than cooler air because the gas molecules in warm air have a greater velocity and are farther apart than in cooler air.

How many grams of hydrogen must react if the reaction needs to produce 31.75 grams of nh3
leva [86]
X= (3*2)(31.75)/(2*17)3*31.75/17
=5.603g H2

Answer: 5.603g H2

It’s all quite simple actually considering the fact the M(NH3) = 14 + 1*3 = 17g/mol
And M(H2) = 2*1 2g/mol

So 3H2 + N2 >> 2NH3

Givin that Xg is 31.75g
