Answer:
190.4g
Explanation:
1.6mol of KBr (119.002g KBr/1 mol) = 190.4g
since you want to find grams, take the molar mass of KBr (119.002) per 1 mol and use it as your conversion factor (119.002g KBr/1 mol) which will then cancel out mols and leave you with grams.
Sodium phosphide is the inorganic compound with the formula Na3P.
Iron (II)
sulfate also known as ferrous sulphate. Its chemical formula is FeSO₄, and
formula weight is the sum of the atomic weights of all atoms that
are present in a given chemical formula.
Molar mass of Fe is 55.8450
g/mol
Molar mass of S
= 32.065 g/mol
Molar mass of
oxygen = 15.999 g/mol
Now add the
masses according to formula:
<span>55.8450 + 32.065
+ 4(15.999) = 151.96 is the formula weight of FeSO</span>₄
Extensive properties such as mass and Volume depend on the amount of matter being measured.
Intensive properties such as density and color do not depend on the amount of the substance present,
Physical properties can be measured without changing a substance's chemical identity.
and Hope this help and i hope you do great on the quiz
Answer:
B. Na
Explanation:
To identify an atom, you simply need to look at the number of protons. This atom has 11 protons. On the periodic table, you can see that the element with 11 protons is sodium (Na).
