Answer:
The answer is
<h2>2.55 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 416 g
volume = final volume of water - initial volume of water
volume = 523 - 360 = 163
volume = 163 mL
The density is

We have the final answer as
<h3>2.55 g/mL</h3>
Hope this helps you
Answer:
Explanation:
concepts, such as the internal energy of a system; heat or sensible heat, which are defined as types of energy transfer (as is work); or for the characteristic energy of a degree of freedom in a thermal system {\displaystyle kT}kT, where {\displaystyle T}T is temperature and {\displaystyle k}k is the Boltzmann constant.
B, the aún gives enough energy for the fossil fuels.
I think
MM Zn(NO₃)₂ = 189.36 g/mol
mass 1 mol Zn(NO₃)₂ = 189.36 g
mass hydrate = 100 / 63.67 x 189.36 = 297.409 g
mass 1 mol hydrate = 297.409 g
MM hydrate = 297.409 g/mol
MM hydrate = MM Zn(NO₃)₂ + MM xH₂O
297.409 = 189.36 + x(18)
x = 6
PH is the logarithmic measure of the concentration of hydrogen ions in solution. In an aqueous system, the lowest possible concentration of H+ ions (least acidic) is 1x 10^-14. The -log(1x10^-14) = pH of 14
