Explanation:
Answer:
946.342ML
Explanation:
I'm assuming ML is milliliter.
mL = qt/0.0010567
mL = 1/0.0010567
mL = 946.342
We can change a gas to a liquid by INCREASING the temperature and DECREASING the pressure
Answer: 27 grams of Be
Explanation: Berylium has a molar mass of 9.0 grams/mole
(9.0 grams/mole)*(3 moles Be) = 27 grams Be
Answer: 0.335 moles
Explanation:
Given that,
Amount of moles of KBr solute (n) = ?
Volume of KBr solution (v) = 0.67 L
Concentration of KBr solution (c) = 0.50M
Since concentration (c) is obtained by dividing the amount of solute dissolved by the volume of solvent, hence
c = n / v
make n the subject formula
n = c x v
n = 0.50M x 0.67L
n = 0.335 moles
Thus, there are 0.335 moles of KBr in 0.67 L of a 0.50 M KBr solution
