2 A certain gas of 25 g at 25°c and 0.65 atm occupies a volume of 23.52L Determine the molecule mass of the gas.

1 answer:

8 0

Answer:

${ \bf{PV= \frac{m}{M} RT}} \\ \\ { \tt{(0.65 \times 23.52) = \frac{25}{M} \times 0.081 \times (25 + 273)}} \\ \\ M = 39.5 \: g$

What is the mass in grams of 394 mL of ethylene glycol? Express your answer with the appropriate units.

AleksandrR [38]

Answer : The mass of ethylene glycol is, 437.34 grams

Solution : Given,

Volume of ethylene glycol = 394 ml

Density of ethylene glycol = 1.11 g/ml (Standard value)

Formula used :

$Density=\frac{Mass}{Volume}$

Now put all the given values in this formula, we get the mass of ethylene glycol.

$1.11g/ml=\frac{Mass}{394ml}$

$Mass=437.34g$

Therefore, the mass of ethylene glycol is, 437.34 grams
