a. To convert 14.8 g to µg (micrograms), we need to multiply by the appropriate conversion factor:
14.8 g * 1,000,000 µg/1 g = 14,800,000 µg
Therefore, 14.8 g is equal to 14,800,000 µg in scientific notation.
b. To convert 3.72 g to kg (kilograms), we need to divide by the appropriate conversion factor:
3.72 g / 1000 kg/1 g = 0.00372 kg
Therefore, 3.72 g is equal to 0.00372 kg in scientific notation.
c. To convert 66.3 L to cm³ (cubic centimeters), we need to multiply by the appropriate conversion factor:
66.3 L * 1000 cm³/1 L = 66,300 cm³
Therefore, 66.3 L is equal to 66,300 cm³ in scientific notation.
d. To convert 7.5 x 10¹ J to kJ (kilojoules), we need to divide by the appropriate conversion factor:
7.5 x 10¹ J / 1000 kJ/1 J = 7.5 x 10⁻² kJ
Therefore, 7.5 x 10¹ J is equal to 7.5 x 10⁻² kJ in scientific notation.
e. To convert 3.9 x 10⁵ mg to dg (decigrams), we need to divide by the appropriate conversion factor:
3.9 x 10⁵ mg / 100 dg/1 mg = 3.9 x 10³ dg
Therefore, 3.9 x 10⁵ mg is equal to 3.9 x 10³ dg in scientific notation.
f. To convert 2.1 x 10 dL to µL (microliters), we need to multiply by the appropriate conversion factor:
2.1 x 10 dL * 10⁵ µL/1 dL = 2.1 x 10⁶ µL
Therefore, 2.1 x 10 dL is equal to 2.1 x 10⁶ µL in scientific notation.
