An example of accurate but not precise would be 3 people weigh a 10g sample. the weights are 0g, 10g, & 20 grams. the scale is way off but the weights average to the right thing.
precise but not accurate would weighing a 10g sample 3 times and getting 5.5, 5.4, & 5.5. they'e all incredibly similar therefore precise but its nowhere near 10, so not accurate.
neither precise nor accurate would be 3 weights being 10, 20, &30. It averages wrong and is imprecise.
Answer:
8.96 g/mL
Explanation:
density = mass / volume
density = 134.3g / 15.0 mL
density = 8.96 g/mL
Answer:
Molecular formula = S₂O
₆
Explanation:
Given data:
Empirical formula = SO₃
Molecular formula = ?
Molecular mass = 152 g/mol
Solution:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Empirical formula mass = 80 g/mol
n = 152 g/mol / 80 g/mol
n = 2
Molecular formula = n (empirical formula)
Molecular formula = 2(SO₃)
Molecular formula = S₂O
₆
I’m not sure but I hope someone tell you
I love you :( ❤️
Answer:
I believe the answer is, 'If mass remains the same while the volume of a substance increases, the density of the substance will decrease.'
explanation: density= mass divided by volume, meaning that volume and density are inversely proportionate.
