The moles that are present in 150 g of ammonium hydrogen phosphite is 1.136 moles
<u><em>calculation</em></u>
<em>The formula of ammonium hydrogen phosphite = (NH4)2HPO4</em>
moles = mass/molar mass
mass= 150 g
molar mass of (NH4)2HPO4 = [ ( 14+ 1x4)2) +1 + 31 + ( 4 x16)] =132 g/mol
moles is therefore = 150 g/ 132 g/mol =1.136 moles
Answer: 101 moles of oxygen are contained in the tank
Explanation:
According to ideal gas equation:
P = pressure of gas = 204.047 atm
V = Volume of gas = 12.0 L
n = number of moles = ?
R = gas constant =
T =temperature =
Thus 101 moles of oxygen are contained in the tank
A, The moon pulls on the earth making the tides rise and fall
Answer:
moves molecules
Explanation:
I did this one yesterday! Active transport moves low to high concentration and passive does the opposite so C and D are not an option. Active transport requires energy and Passive Transport does not so it has to be A.!
