# Question d4d24
Jul 16, 2017
"mass percentage" = 9.33% ${\text{NH}}_{3}$
$\text{molality} = 6.04 m$
#### Explanation:
We're asked to find the mass percentage and the molality of a solution, given the masses of solute and solvent.
The percentage by mass of the solute is given by
%"mass solute" = "g solute"/"g so... |

Real Numbers, Sequences and Series: Part III: Rational Numbers
On Z, we now have unlimited subtraction. Can we divide in Z? In a limited sense, yes. Division is essentially an inverse problem. That is to say, $m \div n$ would stand for a number which when multiplied by n gives m. As long as we are in Z, the question d... |
# What is the GCF of 30 and 80 using prime factorization?
The GCF of 30 and 80 is 10. To calculate the greatest common factor of 30 and 80, we need to factor each number (factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30; factors of 80 = 1, 2, 4, 5, 8, 10, 16, 20, 40, 80) and choose the greatest factor that exactly divides bo... |
