The molar mass of Li->7g/mol
If 1mol of Li is 7g/mol
1.50mol of Li would be 10.5g/mol
Answer:
42996.19989
Explanation:
Molar mass of KCr(SO4)2 12h2o is 20474.3809 g/mol x 2.1 = 42996.19989
The differences are <u>the number of neutrons</u> and the <u>atomic mass</u><u /><u />.
Copper-63 has an atomic mass of 63 amu, and has 34 neutrons.
Copper-65 has an atomic mass of 65 amu, and has 36 neutrons.
1 mole --------- 22.4 L at ( STP )
0.875 moles ----- ?
0.875 x 22.4 / 1 => 19.6 L
hope this helps!
