Density of a solution is mass of solution per unit volume
Density = mass/volume
mass of solution is 46.08 g
volume of solution is 58.9 mL
since mass and volume is known, density can be calculated
density = 46.08 g / 58.9 mL = 0.78 g/mL
The particle that adds mass but no charge to the atomic nucleus is the neutron.
The nucleus contains both protons and neutrons.
Protons and neutrons have about the same mass.
However, protons have a positive charge, while <em>neutrons have no charge</em>,
Answer:
a) 74.87 % carbon
Explanation:
Molecular mass of CH₄ is 16.042 g / mole.
Now we divide the following reasoning for 1 mole of methane:
if in 16.042 g of CH₄ there are 12.01 g of carbon
then in 100 g of CH₄ there are X g of carbon
X = (100 × 12.01) / 16.042= 74.87 % carbon
One atmosphere is equal to 101.3 kilopascals, the measurement of force that the atmosphere exerts at sea level. To convert 112 atmospheres to kilopascals, simply multiply the two together.
112 atm x (101.3 kPa/1 atm) = 11,345.6 kPa
/\
conversion factor
112 atmospheres is the same amount of pressure as 11,345.6 kilopascals.
