Answer:
It depends on whether the setting is hot or cold .-.
Explanation:
Answer:
I think its 1.40M Na^+ we convert to Na3PO4 which means we need 1.40M x (1 mole Na3PO4/3 mol Na^+) = 1.40 x 1/3 = 0.467 M Na3PO4.
Explanation:
Answer:
Molality = 1.13 m
Explanation:
Molality is defined as the moles of the solute present in 1 kilogram of the solvent.
Given that:
Mass of
= 26.5 g
Molar mass of
= 32.04 g/mol
The formula for the calculation of moles is shown below:
Thus,

Mass of water = 735 g = 0.735 kg ( 1 g = 0.001 kg )
So, molality is:

<u>Molality = 1.13 m</u>
Answer:
distance and time are needed to find velocity
