Explanation:
Answer:
As the first order reaction depends on (a uni-molecular reaction) the concentration of only one reactant.
And the rate law of the reaction of first order with a reactant A is:
rate = K[A]^-1
when K is the rate constant.
You take the 1.00 M and multiply it by 375L witch gives you 375mol and then you take the mol and multiply it by the molar mass giving you 23630.505g nitric acid or HNO3
X4O10
Let molar mass of X be y
molar mass = 4y + 10 x 16 = 4y+160
so, moles = 85.2 / (4y+160)
Moles of oxygen = 10 x [85.2 / (4y+160) ]
Mass of oxygen = 16 x 10 x [85.2 / (4y+160) ]
which is 48.0
so, 48 = 16 x 10 x [85.2 / (4y+160) ]
Solve the equation to get y.
y = 31
They are all examples of chemical formulas
