The diameter of the model would be
63.1 m.
The diameter of a hydrogen atom is 1.06 × 10⁻¹⁰ m.
The diameter of a proton is 1.68 × 10⁻¹⁵ m.
The ratio of their diameters is
= 6.31 × 10⁴
So the diameter of your model would be 6.31 × 10⁴ mm
.
6.31 × 10⁴ mm ×
= 63.1 m
Answer:
a. 0.0855 M
b. 0.153 M
c. 0.0351 M
d. 0.0901 M
Explanation:
a.
Molar mass NaCL= 23.0 +35.5 = 58.5 g/mol
10.0 g* 1 mol/58.5 g = 10.0/58.5 mol
(10.0/58.5) mol/2L = 0.0855 mol/L = 0.0855 M
b.
Molar mass (C12H22O11) =342.3 g/mol
52.5 g*1mol/342.3 g = 52.5/342.3 mol=0.153 mol
0.153 mol/1L = 0.153 M
c.
Molar mass (Al2(SO4)3) =342.2 g/mol
120g* 1 mol/342.2 g =0.351 mol
0.351 mol/10.0L = 0.0351 mol/L = 0.0351 M
d.
Molar mass (C8H10N4O2) = 194.2 g/mol
1.75 g*1mol/194.2 g = 0.00901 mol
0.00901 mol/0.100 L =0.0901 M
A material is a mixture if it is not pure
In these atoms, the positive and negative charges cancel each other out, leading to an atom with no net charge.
(Protons, neutrons, and electrons)
We see from the balanced equation that there is only 1
mole to 1 mole ratio.
Calculate moles of AgNO3:
moles AgNO3 = 0.2503 M * 0.02022 L = 0.00506 mol
This is equal to moles of NaCl,
moles NaCl = 0.00506 mol
So the concentration is:
<span>Concentration = 0.00506 mol / 0.015 L = 0.3374 M</span>
