Answer:
The molarity of a 50.0 mL solution that contains 0.0350 mol of sodium sulfate 0.7 
Explanation:
Molarity is a concentration measure that indicates the amount of moles of solute that appear dissolved in each liter of the mixture.
So, the Molarity of a solution is determined by the expression:
Molarity is expressed in units ().
In this case:
- Volume=50 mL=0.05 L (1 L= 1,000 mL)
Replacing:
Molarity= 0.7
<u><em>The molarity of a 50.0 mL solution that contains 0.0350 mol of sodium sulfate 0.7 </em></u><u><em></em></u>
Answer:
the volume of water with egg was 200 and when we removed the egg become 125
Explanation:
200ml - 125ml = 75ml
so 1 millimeter = 1 centimeter cubic
so
75ml = 75 cm3
the answer is 75cm3
Answer:
Its a small dense spherical structure in the nucleus of a cell during interphase.
Given :
A balanced chemical equation :
To Find :
How many grams of zinc are needed to produce 12 grams of zinc chloride.
Solution :
Moles of 
,
Now, by balanced chemical equation we can say that 1 mol of Zn produce
1 mol of .
So, 0.088 mol of Zn is required to produced 0.088 mol of .
Therefore, 5.8 grams of zinc is required.
Hence, this is the required solution.
Answer:
As there are many units of mass and volume covering many different magnitudes there are a large number of units for mass density in use. The SI unit of kilogram per cubic metre (kg/m3) and the cgs unit of gram per cubic centimetre (g/cm3) are probably the most commonly used units for density.
