Molar mass H₂SO₄ = 98.0 g/mol
Volume = 1.290 L
number of moles:
153.3 / 98 => 1.564 moles
M = n / V
M = 1.564 / 1.290
M = 1.212 mol/L

The formula of the hydrate = CuSO₄• 3H₂O
<h3>Further explanation</h3>
Given
4.175 grams sample CuSO₄• xH₂O
3.120 grams anhydrous compound CuSO₄
Required
The formula
Solution
mass of H₂O driven off :
= 4.175 - 3.12
= 1.055 g
MW CuSO₄ = 159.5 g/mol
MW H₂O = 18 g/mol
mol ratio of CuSO₄ : H₂O :
= 3.12/159.5 : 1.055/18
= 0.01956 : 0.05861
= 1 : 3
Answer:
When there is less carbon (in the form of carbon dioxide) in abiotic matter, less carbon is available for producers making energy storage molecules. When there is more sunlight, producers can make more energy storage molecules from the carbon in carbon dioxide.
Hope this helps.
From the combined gas law
that is P1V1/T1=P2V2/T2
P2 is therefore T2P1V1/TIV2
A gas at STP has a temperature of 273k and a pressure of 760torr
P1=760torr
T1=273K
V1=6ml
P2=?
T2=525+273=798K
V2=500ml
P2 ={(798k x760 torr x 6ml) /(273k x500ml)} = 26.7 torr
