Answer:
100g
Explanation:
The law of the conservation of mass states that atoms cannot be created nor destroyed, thus in a chemical reaction the sum of the mass of the reactant always equal the sum of the mass or the products. 75g of sodium plus 25g chlorine would combine to make 100g of sodium chloride

Answer:
3.94 atm
Explanation:
Using the general gas law equation as follows;
PV = nRT
Where;
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = gas law constant (0.0821 Latm/molK)
T = temperature (K)
According to the information provided in this question;
P = ?
V = 50 L
T = 300K
n = 8 mol
Using PV = nRT
P = nRT/V
P = (8 × 0.0821 × 300) ÷ 50
P = 197.04 ÷ 50
P = 3.94 atm
