Answer:
0.98 M
Explanation:
Given data:
Mass of sugar = 20 g
Mass of water = 59 g
Concentration of solution = ?
Solution:
1 g = 0.01 L
59 g× 0.01 L/1 g
0.059 L
Concentration formula:
C = m/v
m = moles of solute
v = volume of solution
Number of moles of sugar:
Number of moles = mass/molar mass
Number of moles = 20 g/ 342.3 g/mol
Number of moles = 0.058 mol
Now we will calculate the concentration:
C = 0.058 mol/0.059 L
C = 0.98 mol/L
C = 0.98 M
Answer:
0.2425 M
Explanation:
Given mass = 9.36 g
Molar mass of NaOH = 39.997 g/mol
The formula for the calculation of moles is shown below:
Thus,
Given that:- Volume = 965 mL = 0.965 L ( 1 mL = 0.001 L )
So,
Considering:
The answer is covalent bond!
<em>Data collected from moonquakes shows that ______;</em>
The center of the moon may be molten
<u>Convection in the molten zone makes moonquakes possible. These moonquakes are usually triggered by tidal forces coming from Earth.</u>
Answer:
The valency of Aluminium (Al) is +3 whereas, the valency of Chlorine is -1.
Explanation:
Valency is not defined for a compound. It is only for elements. Basically, valency is the combining or replacing power of an hydrogen atom of a certain element with an other atom of element.
