I have written it out and explained it. I hope it helps! Here:
The formula for calculating the density (p)=m/v
m:mass
v:volume
<u>Explanation:</u>
In the question above,given that
<u>mass of water (m)</u> =100 g
<u>Volume of water in a beaker (v)</u>=100 mL
<u>The Density of the water(p</u>)=m/v=100 g/100 mL= 1 g/mL
The answer is (B) 1 g/mL
False
Actual yield in a reaction is almost always less than the theoretical yield, primarily because losses of the substances involved may occur anywhere in an experiment. Otherwise, there can be so many possibilities that can be reasoned out depending on the reaction.
Answer: 0.58 moles
Explanation: Using ideal gas equation:
PV = nRT
P= pressure =500 kPa=4.93 atm [1 kPa= 0.009atm]
V= volume =3 L
n = no of moles = ?
R= gas constant =0.0821 Latm\molK
T= temperature = 310K
