To determine how many grams of sodium acetate (C_{2}H_{3}O_{2}Na)
1. **Determine your starting and desired units.**
- The starting unit is grams of baking soda (NaHCO_{3})
- The desired unit is grams of sodium acetate (C_{2}H_{3}O_{2}Na)
2. **Convert from grams of baking soda (NaHCO_{3})
- Use the molar mass of NaHCO_{3}
3. **Convert from moles of baking soda (NaHCO_{3})
- Use the stoichiometric coefficients from the balanced chemical equation to find the mole ratio between NaHCO_{3}
4. **Convert from moles of sodium acetate (C_{2}H_{3}O_{2}Na)
- Use the molar mass of C_{2}H_{3}O_{2}Na
So, the correct order of the steps is:
1. Determine your starting and desired units.
2. Convert from grams of baking soda (NaHCO_{3})
3. Convert from moles of baking soda (NaHCO_{3})
4. Convert from moles of sodium acetate (C_{2}H_{3}O_{2}Na)
you expect to form from 2.9 grams of baking soda (NaHCO_{3})
, you need to follow these steps in order:
1. **Determine your starting and desired units.**
- The starting unit is grams of baking soda (NaHCO_{3})
.
- The desired unit is grams of sodium acetate (C_{2}H_{3}O_{2}Na)
.
2. **Convert from grams of baking soda (NaHCO_{3})
to moles of baking soda (NaHCO_{3})
using molar mass.**
- Use the molar mass of NaHCO_{3}
to convert grams to moles.
3. **Convert from moles of baking soda (NaHCO_{3})
to moles of sodium acetate (C_{2}H_{3}O_{2}Na)
using mole ratio.**
- Use the stoichiometric coefficients from the balanced chemical equation to find the mole ratio between NaHCO_{3}
and C_{2}H_{3}O_{2}Na
.
4. **Convert from moles of sodium acetate (C_{2}H_{3}O_{2}Na)
to grams of sodium acetate (C_{2}H_{3}O_{2}Na)
using molar mass.**
- Use the molar mass of C_{2}H_{3}O_{2}Na
to convert moles to grams.
So, the correct order of the steps is:
1. Determine your starting and desired units.
2. Convert from grams of baking soda (NaHCO_{3})
to moles of baking soda (NaHCO_{3})
using molar mass.
3. Convert from moles of baking soda (NaHCO_{3})
to moles of sodium acetate (C_{2}H_{3}O_{2}Na)
using mole ratio.
4. Convert from moles of sodium acetate (C_{2}H_{3}O_{2}Na)
to grams of sodium acetate (C_{2}H_{3}O_{2}Na)
using molar mass.
