Answer:
1.48381734165x 10²⁵ molecules
Explanation:
1 grams CuNo3 is equal to 0.0011897028836018 mole.
x = 5.5 moles
x = 5.5 x 1/0.0011897028836018 = 5.5/0.0011897028836018
4623.003grams
the molar mass of cuno3 =187.56 = 6.02 x10²³
4623.003g = x
187.56x = 4623.003 x 6.02 x10²³ = 27830.47806 x10²³ = 1.48381734165x 10²⁵
Answer:
C ) Cu(s) + 2AgNO3(aq)
Explanation:
A chemical reaction is represented by a chemical equation which show the reactant and products. Reactants are written on left side of arrow while products are written on right side. The number of atoms are remain same however arrangement of atoms is different on both side.
For example:
Cu(s) + 2AgNO3(aq) → 2Ag + Cu(NO3)2
In this reaction Cu and AgNO3 are reactants while Ag and Cu(NO3)2 are products.The number of atoms are same on both side however arrangement of atoms is different.
Because it is a lot closer to us then any of the stars are....
You may have noticed that the nearer a thing is to you, the larger it looks,and the farther.
N = m/M
Where,
n = number of moles
m = mass of substance
M = molar mass of substance
0.8286 = m / 30.067
Multiply both sides by 30.067
m = 24.9135162g
