Answer:
<h2>The answer is 615 g</h2>
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 seawater = 600 mL
density = 1.025 g/mL
The mass is
mass = 600 × 1.025
We have the final answer as
<h3>615 g</h3>
Hope this helps you

<u>Answer</u>:
According to Bohr's theory, an electron's path around the nucleus defines its
energy level.
<u>Explanation</u>:
It the certain energy by which the electrons have occupied there place in the orbitals. They can also be moved to the higher energy level by taking the energy from the surrounding. The emission of light can be seen when the electron falls from the higher energy state to the lower state. The orbital that is close to the atomic centre having the lowest energy level and the one that is found to be far away from the atomic centre has the highest energy level.
Hello!
Three nails have a mass of 3.05 g. How many moles of iron do they contain?
Data:
3 nails of iron = 3.05 g (by nail)
The atomic mass of iron is 55.845 amu, so the molar mass is:
M = 55.845 → M ≈ 56 g / mol
With a simple 3 rule:
56 g → 1 mol
3.05 g → y mol
Therefore:
Soon:
3 nails → 3*0.05446 = 0.1638 moles (answer)
