Answer:
It only needs one electron.
Kelvin (K) is the only scale that has a numeral value assigned to absolute zero.
So we know that the equation for density is:
where D is the density, m is the mass in grams, and V is the volume in mL.
So since we know two of the variables, mass and density, we can solve for the volume:
Therefore, the volume of this urine sample is 144.12mL.
4. 4 C + S8 = 4 CS2
5. H2 + O2 = H2O2 is already balanced.
6. 4 Na + O2 = 2 Na2O
Answer:
[ Ga ] = 1.163 E-8 Kg/m³
Explanation:
- %wt = [(mass Ga)/(mass Si)]*100 = 5.0 E-7 %
⇒ 5.0 E-9 = m Ga/m Si
assuming: m Si = 100 g = 0.1 Kg
⇒ m Ga = (5.0 E-9)*(0.1 Kg) = 5 E-10 Kg
∴ density (δ) Si = 2.33 Kg/m³
⇒ Volume Si = (0.1 Kg)*(m³/2.33 Kg) = 0.043 m³
⇒ [ Ga ] = (5 E-10 Kg)/(0.043 m³) = 1.163 E-8 Kg/m³
⇒ [ Ga ] =
