Explanation:
5.5 moles
2.0=x/2.75
2.0*2.75= x/2.75 (2.75)
5.5=x
Answer:
new volume is 1215mL
Explanation:
using Charles law , the volume of a fixed mass of gas is directly proportional to its temperature provide that pressure is kept constant.

V1=900mL ,
convert the temperatures from Celsius to kelvin temperature.
T1 =27°C =27+273 =300K
T2 =132°C = 132+273=405K


V2= 1215mL
Answer:
4800 times a day
Explanation: she blinks 300 times every hour and i times it by 16 as the hours everyday (24-8) so 300 x 16 equals 4800
