The unit of measurement for weight is that of force, which in the International System of Units (SI) is the newton. For example, an object with a mass of one kilogram has a weight of about 9.8 newtons on the surface of the Earth, and about one-sixth as much on the Moon.
Answer:
[Ar] 4s2 3d10 4p3
Explanation:
Arsenic is Element 33. It is the 15th element in the Fourth Row, following the noble gas Ar at the end of the Third Row.
Thus, its noble gas electron configuration is
[Ar] 4s2 3d10 4p3
Answer:
Explanation:
Li+H2O..................LiOH+H2
mass of Li=17.8 g
No of moles of Li=17.8/7=2.5
mass of H2O=50.0 g
No of moles of H2O=50.0/18=2.8
limiting reagent is Li so 1 mole of Li produce 1 mole of LiOH therefore 2.5 mole of Li produce 2.5 moles of LiOH now we have to convert it into grams
moles=given mass/molar mass
given mass=moles*molar mass
molar mass of LiOH=24
mass=2.5*24=60 gram
Using the formula density = mass ÷ volume, I got my answer as 10g/cm^3 or 10g/mL
