Follow Avogadro’s Number
1 mole = 6.02 x 10^23
So we can do it
4.77x10^25/6.02x10^23 = 79.2 mole
Answer:
i assume that it would be a gametophyte.
Explanation:
YEs grass does have cells because it is still alive
Answer is: Move from the negatively charged body to the positively charged body.
The electron (symbol: e⁻) is a subatomic particle whose electric charge is negative one elementary charge.
The proton (p⁺) is subatomic particle with a positive electric charge of +1e elementary charge.
Opposite charges (positive and negative) attract one another.
The negatively charged body has extra electrons, more electrons than protons.
The positively charged body has less electrons than protons.
Hey there!
Consider 100 g of solution:
Mass of NaCl = 3.50% of mass of seawater
( 3.50 / 100 ) * 100 => 3.50 g
Number of moles as shown below:
Molar mass NaCl = 58.44 g/mol
n = Mass / molar mass
n = 3.50 / 58.44 => 0.059 moles of NaCl
Mass of sweater:
Mass of solution - Mass of NaCl
100 - 3.50 = 96.5 g
96.5 g in Kg :
96.5 / 1000 => 0.0965 Kg
Therefore ,calculate molality by using the following formula:
molality = number of moles of solute / mass of solution
molality = 0.059 / 0.0965
molality = 0.61 m
Hope That helps!
