Question

If 1.0 mL of a solution containing 1M NaOH and NaBH4 (80 mg/1 mL of solution) was used, calculate the moles of NaBH4 used.
Relevant Information about NaBH4: MW = 37.83 g/mol MP = 400 Celsius BP = dec. Concentration = 80 mg/mL

If 1.0 mL of a solution containing 1M NaOH and NaBH4 (80 mg/1 mL of solution) was used, calculate the moles of NaBH4 used.
Relevant Information about NaBH4: MW = 37.83 g/mol MP = 400 Celsius BP = dec. Concentration = 80 mg/mL


Relevant Information about NaBH4: MW = 37.83 g/mol MP = 400 Celsius BP = dec. Concentration = 80 mg/mL

Explanation / Answer

80 mg per mL

moles = weight in grams / molecular weight

moles of NaBH4 = 0.08grams/ 37.83

= 0.002114 moles
