Answer:
895.8g/mol
Explanation:
Hello, here the solution:
Consider the formula for the boiling-point elevation:
We solve for the molality of the solute:
By knowing the mass of the diethyl ether (271.8 g =0.2718kg) and that 11.20g of the solute were dissolved, the molecular mass is given by:
Best regards.
6000 that should be the answer if u are doing it by thousands
Sound waves travel faster trough the graouund because the particles are more closely packed together so it would be B as your answer
ANSWER: B
