Percentage of MgSO4 = mass of MgSO4/ mass of sample (MgSO4. 7H20) and multiply it by 100.
THE ANSWER
for solving this, we just use the formula of the equation of state
PV = n RT
where
P: pressure =10atm
V volume
n number of mole = 35.8 moles
R universal gas constant = 0.082
T: The temperature= 70°C= 343.15 Kelvin
therefore, for finding V
we have
V= (n RT) / P = 35.8 x 0.082 x 343.15 / 10 = 100.7 ≈ 101 L
the answer is V = 101L
The pH of the solution will be lowered. Currently the solution is Neutral (salt water). Adding an acid will turn the solution slightly acidic
Answer:
Electrons are particles that surround the nucleus of an atom like a cloud. As with protons and neutrons, electrons are essential to an atom's structure.
