Answer key: Brine worksheet
Calcapedia 1. Salt: 100.8 g
Change the water into grams so everything is weighed the same way. 1 mL of water weighs about 1 g
Add the food's weight to the water's, because in this kind of brine the salt spreads into both
Take 1.8% of that combined weight for the salt
2. Salt: 204 g
Change the water into grams so everything is weighed the same way. 1 mL of water weighs about 1 g
Find the water's share of the finished brine: whatever is left after the salt and sugar shares
Multiply the water by the salt share, then divide by the water's share. That makes salt the chosen share of the whole brine
Work out the sugar the same way, using the sugar share
Check the answer: the salt divided by the whole brine's weight gives back your chosen percentage
3. Salt: 205.7 g
Change the water into grams so everything is weighed the same way. 1 mL of water weighs about 1 g
Find the water's share of the finished brine: whatever is left after the salt and sugar shares
Multiply the water by the salt share, then divide by the water's share. That makes salt the chosen share of the whole brine
Work out the sugar the same way, using the sugar share
Check the answer: the salt divided by the whole brine's weight gives back your chosen percentage
4. Salt: 162.5 g
Change the water into grams so everything is weighed the same way. 1 mL of water weighs about 1 g
Find the water's share of the finished brine: whatever is left after the salt and sugar shares
Multiply the water by the salt share, then divide by the water's share. That makes salt the chosen share of the whole brine
Work out the sugar the same way, using the sugar share
Check the answer: the salt divided by the whole brine's weight gives back your chosen percentage
5. Salt: 84.6 g
Change the water into grams so everything is weighed the same way. 1 mL of water weighs about 1 g
Add the food's weight to the water's, because in this kind of brine the salt spreads into both

6. Salt: 496.4 g
Change the water into grams so everything is weighed the same way. 1 mL of water weighs about 1 g
Find the water's share of the finished brine: whatever is left after the salt and sugar shares
