Answer:
Moles of substance are defined ratio of the given mass of the substance to the molar mass of the substance.
Given :
The 52.06 grams of carbon dioxide.
To find :
The moles of carbon dioxide.
Solution:
The mass of carbon dioxide = 52.06 g
The molar mass of carbon dioxide = 44.01 g/mol
The moles of carbon dioxide:
1.183 moles of carbon dioxide are there in 52.06 g of carbon dioxide.
Explanation:
Answer: Volume occupied by given neon sample at standard condition is 123.84 L.
Explanation:
Given: 
= 105 L, 
, 
= 985 torr
At standard conditions,
= 273 K, 
= 760 K, 
= ?
Formula used to calculate the volume is as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that volume occupied by given neon sample at standard condition is 123.84 L.
Answer:
449.5 g
Explanation:
Silver sulfate- Ag2SO4
M(Ag)=107 g/mol => M(Ag2)=214 g/mol
M(S)=32 g/mol
M(O)=16 g/mol => M(O4)=64 g/mol
M(Ag2SO4)=310 g/mol
n=1.45 mol
m(Ag2SO4)=M(Ag2SO4)*n=310 g/mol *1.45 mol= 449.5 g
Vinegar is a mixture cause its composed of water and acetic acid.
