Molarity is a concentration unit, the number of moles of solute divided by the numbers of liters in a solution. Pertaining to chem
Answer:
D
Explanation:
When substrate molecules bind to the active site of the enzyme, the enzyme undergoes a slight change in shape.
The answer is 0.5010
Number of moles (n) is equal to the quotient of mass (m) and molar mass of a sample (Mr):
n = m/Mr
We have:
n = ?
m = 40.10 g
Mr = 80.0432 g/mol
n = 40.10 g : 80.0432 g/mol = 0.5010
<span>40.10 has 4 significant digits,
</span><span>80.0432 has 6 significant digits.
Since 4 is less than 6, we choose 4 </span>significant digits
