Answer:
d) 44 g/mol
Explanation:
If we can consider that this gas behaves like an ideal gas, then we can use the following formula:
PV=nRT
P=pressure
V=volume
n=N° of moles
R= gas constant, it has multiple units, for this case, we will use 62.36 mmHg*Lt/mol*K
Then, the number of moles can also be noted as:
n=m/M , where m=mass and M=molar gas so: PV=(m/M)RT
M=(mRT)/(PV)
And we have the rest of the values for this case:
T=0°=273°K
V=1Lt
P=238 mmHg
m=0.614 g
If we finally put all these values in our formula, we can get the molar mass for this gas:
M=(0.614x62.36X273)/(273x1) gxmmHgxLtx°K/molx°K/(mmHgxLt)
M= 44 g/mol

Answer: You need the mass of the bat and the length in some-type of units.
Explanation:
Answer:
Shampoo < corn syrup < honey
Explanation:
Shampoo flows fairly easily from the bottle, so would say it is the least viscous.
Both honey and corn syrup are quite viscous.
However, honey can range from liquid to solid at room temperature.
I have not seen solid corn syrup, so I would predict that it is less viscous than honey at a given temperature.
