Its like weight but not. mass is the amount of matter in a substance.
Answer:
4057.85 g/mol
Explanation:
Hello, the numerical procedure is shown in the attached file.
- In this case, since we don't have the density of the protein, we must assume that the volume of the solution is solely given by the benzene's volume, in order to obtain the moles of the solute (protein).
-Van't Hoff factor is assumed to be one.
Best regards.
A) probably some thin metal would work
B) Medium strength
C) either an electron or positron
D) 9.11x10^-31 kg
Answer:
(a) (b)
Explanation:
The reaction that is carried out by the enzyme catalase produces
The reaction that is carried out by the enzyme catalase produces
Answer:
Explanation:
First, we must find the density of the unknown metal.
Density is found by dividing the mass by the volume.
The mass of the metal is 89 grams and the density is 10 cubic centimeters.
Substitute the values into the formula.
Divide.
Now we know the density and can identify the unknown metal.
- Nickel: 8.9 g/cm³
- Silver: 10.5 g/cm³
- Lead: 11.35 g/cm³
- Mercury: 13.55 g/cm³
The density matches nickel's density. Therefore, this metal must be <u>nickel.</u>
