The
amount of a substance can be converted into grams of that substance by using
the molar mass. It is a physical property of a substance which describes the
mass per mole of the substance. The molar mass of Zn is 65.38 g/ mol.
Multiplying the given amount of Zn with the molar mass will yield to the
mass of the substance.<span>
</span>
<span>1.0 x 10^-3</span><span> x 65.38 =</span><span> </span><span>0.0654 g Zn</span>
Answer:
V₂ = 453.125 mL
Explanation:
Given data:
Initial volume = 25.0 mL
Initial molarity = 1.45 M
Final molarity = 0.0800 M
Final volume = ?
Solution:
Formula:
M₁V₁ = M₂V₂
Now we will put the values in formula.
1.45 M × 25.0 mL = 0.0800 M × V₂
V₂ = 1.45 M × 25.0 mL / 0.0800 M
V₂ = 36.25 M.mL / 0.0800 M
V₂ = 453.125 mL

Answer:
A prediction that a tire'a air pressure will increase if the tire's temperature is raised.
Explanation:
T k = 15 + 273 = 288 K
4.6 / 13 => 0.353 atm
0.50 / 0.10 => 5 L
<span>(15 + 273) K x (13 atm / 7.6 atm) x (0.50 L / 0.10 L)
</span>
<span>= </span>2463.15 K
<span>hope this helps!</span>
