Answer:
<h3>The answer is 112.36 g</h3>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
<h3>mass = Density × volume</h3>
From the question
volume of liquid = 53 mL
density = 2.12 g/mL
We have
mass = 2.12 × 53
We have the final answer as
<h3>112.36 g</h3>
Hope this helps you
Answer:
The number of Chlorine atoms in the product is 2.
Explanation:
The law of conservation of mass states that matter can neither be created nor destroyed in a chemical reaction.
The reactants contain one chlorine molecule() which has two chlorine atoms.
Then, according to law of conservation of matter, the product must contain two chlorine atoms.
We can use the combined gas law equation to find the new pressure of the gas.
where P - pressure
V - volume
T - temperature
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
P1 - 795 mm Hg x 0.0013 atm/ mm Hg = 1.033 atm
T1 - 23.5 °C + 273 = 296.5 K
T2 - 31.7 °C + 273 = 304.7 K
substituting the values in the equation
P = 0.712 atm
the answer closest to this value is A) 0.723 atm
therefore answer is
<span>A) 0.723 atm</span>
