Answer:
The density of this solution is 2.2 g/mL
Option 3 is correct
Explanation:
Step 1: Data given
Volume = 10.0 mL
mass = 22 grams
Step 2: Calculate the density
Density = Mass / volume
Density = 22.00 grams / 10.0 mL
Density = 2.2 grams / mL
The density of this solution is 2.2 g/mL
Option 3 is correct
Answer:
7.8 grams per cm
Explanation:
to get density you need the mass and volume then you divide them so
81.9 grams/10.5 cm gives 7.8g/cm
Answer:
There are seven (7).
Explanation:
Since 5 digits are not zero and they're before the zero, they're automatically sig figs.
Since there's a sig fig (#4) after the zero, zero and the # 4 are also sig figs.
Added together, they're are seven
