Answer:
Estuaries have more concentrated nutrients and less concentrated salt.
Answer:
<h2>mass = 19.98 g</h2>
Explanation:
To find the mass of 1.11 mol of H2O we must first find it's molecular mass after that we use the formula
<h3>m = M × n</h3>
where
m is the mass
M is the molecular mass
n is the number of moles
From the question
n = 1.11 mol
Taking
M( H) = 1 g/mol , M(O) = 16 g/mol
We have
M( H2O) = 2 + 16 = 18 g/mol
So we have
m = 1.11 × 18
We have the final answer as
<h3>mass = 19.98 g</h3>
Hope this helps you
D neutrons. Theoretically, isotopes have different atomic mass but they do have a similar no. of protons. Having said that, subtracting protons with the different atomic masses results in different no. of neutrons.
Answer:
Explanation:
We will need a balanced chemical equation with masses and molar masses, so, let's gather all the information in one place.
MM: 74.12 184.24
CH₃CH₂CH₂CH₂OH + (C₆H₅)₂CHOH ⟶ Product
m/g: 1.30
ρ/g·mL⁻¹: 0.8098
1. Moles of benzhydrol (BH)
2. Moles of butan-1-ol (BuOH)
The molar ratio is 1 mmol BuOH:1 mmol BH.
3. Mass of BuOH
4. Volume of BuOH
