Answer:
3.5 Molar
Explanation:
Molarity = no of moles/ volume of solution in liter
Molarity = 1.75/0.50
Molarity = 3.5 molar
According to this formula:
(P1V1) / T1 = (P2V2) / T2
convert T from C° to Kelvin:
T1 = 83 + 273 = 356 K
T2= 96 + 273 = 369 K
convert P from torr to atm:
1 torr = 0.00131578947 atm<span>
p1 = 0.839474 atm
P2 = 1.415789 atm
By substitution in the previous formula:
(0.839474 x 10.6 ) / (356) = ( 1.415789 x V2 ) / 369
So:
V2 = 6.5 L</span>
Answer:
54 g
Explanation:
To solve this problem we will simply follow the Law of conservation of mass.
According to this law:
" The mass of product in the chemical reaction must be equal to the mass of reactant"
Given data:
mass of methane= 24 g
mass of oxygen= 96 g
mass of carbon dioxide= 66 g
mass of water= ?
Solution:
CH4 + 2O2 → CO2 +2H2O
24g + 96 g = 66 g + ?
120 g = 66 g + ?
120 g - 66 g = 54 g
so 54 g of waters are produce.
We can see that mass of water is equal to the sum of masses of reactant minus mass of product formed i.e mass of carbon dioxide.
