1 tablet
Explanation:
Assuming that gm stands for gram:
Put everything in one unit, 0.3 g = 300 mg.
And given that each tablet is 300 mg:
mass/amount = 300mg / 1 tablet
300mg / X amount = 300mg / 1 tablet
(300mg/300mg) tablet = X = 1 tablet
So it is 1 tablet you need.
Mole is equal to 6.02*10^23 atoms, and you have 7.00*10^23 atoms
Answer:
The answer is 20 % V/V
Explanation:
We use this formula for calculate the %V/V:
%V/V= (ml solute/ml solution) x 100= (75ml/375 ml)x 100 = 20 % V/V
<em>The% V / V represents the amount of ml of solute dissolved in 100 ml of solution</em>
