The basic building block of matter is the atom.
Answer:
0.2007 nm
3.57 cm
0.01478 g
8280000 pg
Explanation:
1)200.7 pm
1 picometer is equal to 0.001 nanometer.
1 nm = 1000 pm
200.7 pm× 1 nm / 1000 pm = 0.2007 nm
2)0.000357 hm
1 hectometer is equal to 10,000 centimeter.
1 hc = 10,000 cm
0.000357 hc× 10,000 cm / 1 hc = 3.57 cm
3) 14.78 mg
1 gram is equal to 1000 milligram.
1 g = 1000 mg
14.78 mg × 1 g/1000 mg = 0.01478 g
4)8.280 µg
1 microgram is equal to 10⁶ picogram.
1 µg = 1000000 pg
8.280 µg× 10⁶ pg/ 1µg = 8.280×10⁶ pg or 8280000 pg

A transverse and longitudinal wave combine to form a Water Wave.
Answer:
Molecular formula = S₂O
₆
Explanation:
Given data:
Empirical formula = SO₃
Molecular formula = ?
Molecular mass = 152 g/mol
Solution:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Empirical formula mass = 80 g/mol
n = 152 g/mol / 80 g/mol
n = 2
Molecular formula = n (empirical formula)
Molecular formula = 2(SO₃)
Molecular formula = S₂O
₆
