Answer:
34.9103 or 34.9 g
Explanation:
Remember Density is a broken heart: m/v.
In this scenario (Let x = # of grams in the sample of gasoline),
D = 0.7198 g/mL = x g / 48.5 mL
So,
(0.7198 g/mL) * (48.5 mL) = x g
x g = 34.9103 = 34.9 g (Accounting for Significant Figures)
Answer:
Oh so so sorry about that. and thanks for caring for us. anyway we are good wbu
Answer:
percent error = - 99.134 %
Explanation:
Given data:
measured length = 1.85 cm
accepted or given value length = 2.15 m
percent error = ?
Solution:
First of all we will convert the length in meter into cm.
1 meter = 100 cm
2.15 × 100 = 215 cm
Formula:
percent error = (measured value - accepted value/ accepted value) × 100%
Now we will put the values in equation
percent error = (1.85 cm - 215 cm/ 215 cm) × 100%
percent error = -0.9914 × 100%
percent error = - 99.134 %
