Answer:
Mass of O = 8.2 gram
Explanation:
Given:
Mass of Fe = 10 g
Total volume = 18.2 g
Find:
Mass of O
Computation:
Using Conservation of total mass
Total volume = Mass of O + Mass of Fe
18.2 = Mass of O + 10
Mass of O = 8.2 gram
Answer:
0.8853 mL
Explanation:
First we <u>convert 13 lb to kg</u>, keeping in mind that <em>1 lb = 0.454 kg:</em>
- 13 lb *
= 5.902 kg
Then we <u>calculate how many mg of acetaminophen should be given</u>, using the <em>recommended dose and infant mass</em>:
- 15 mg/kg * 5.902 kg = 88.53 mg
Finally we<u> calculate the required mL of suspension</u>, using its <em>concentration</em>:
- 88.53 mg ÷ (80 mg/0.80 mL) = 0.8853 mL
FeO·TiO₂
w(Ti)=M(Ti)/M(FeO·TiO₂)
w(Ti)=47.88g/mol/151.73g/mol=0.3156 (31.56%)
Answer:
Rise in charge reduced the size due to rise in attraction between electron and nucleus.
Explanation:
Ion of magnesium is smaller than the atom of magnesium. As the nuclear charge increases, the attraction of electron to the nucleus increases in charged ions form of any element. Due to this increase in charge of magnesium ion, the size of ion reduces
No. of electrons in Mg = 12
No. of proton in Mg = 12
Where as
No. of electrons in Mg2+ = 12
No. of proton in Mg2+ = 10
