Answer:
The answer is
<h2>1.45 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass of material = 5.01 g
volume = 3.46 mL
The density of the material is

We have the final answer as
<h3>1.45 g/mL</h3>
Hope this helps you
The correct answer is 2.53 g of precipitate, BaCrO4.
Answer: 4.15234 m
512 g H2O *
= 0.512 kg H2O
Nitric Acid: HNO3 = 1.008 + 14.007 + 3(15.999) = 63.012 g/mol
H = 1.008 g/mol
N = 14.007 g/mol
O3 = 3*15.999
134 g HNO₃ *
= 2.126 mol
m =
= 4.15234 m
