How much would 275.0 mL of ethyl alcohol weigh ?
use the formula
Density = mass / volume
mass = density x volume
he has given the volume = 275.0 mL
density of ethylene gly col = 1.11 g / mL
now weight = 275.0 mL x 1.11 g / mL
= 305.25 g
(a) If a 500-mL glass beaker is filled to the brim with ethyl alcohol at a temperature of 5.00ºC, how much will overflow when its temperature reaches 22.0ºC? The coefficient of volume expansion for glass is 27x10-6 and for ethyl alcohol is 1100x10-6. (b) How much water would overflow under the same conditions? The coefficient of volume expansion for water is 210x10-6.
If a 490 mL ordinary glass beaker is filled to the brim with ethyl alcohol at a temperature of 6.00°C, how much (in mL) will overflow when their temperature reaches 22.0°C? mL (b) How much less water would overflow under the same conditions? mL
If a 150 mL glass beaker is filled to the brim with ethyl alcohol at a temperature of 8.20°C, how much will overflow (in mL) when the alcohol's temperature reaches the room temperature of 21.0°C? (Assume the beaker is initially at room temperature.) How much less water (in mL) would overflow under the same conditions?
(a) If a 550-mL ordinary glass beaker is filled to the brim with ethyl alcohol at a temperature of 3.50°C, how much will overflow when their temperature reaches 22.0°C? The coefficient of volume expansion for ethyl alcohol is 1100 ✕ 10−6/°C. Assume the change in volume of the glass beaker is negligible compared to that of the liquid. mL (b) How much less water would overflow under the same conditions? The coefficient of volume expansion for water is 210 ✕...
