<span>The weight of the precipitate was 17.550g - 17.410g = 0.140g. From a 10ml sample, this means the concentration was 0.140g / 10ml, which is equal to 0.014g/ml.</span>
The average speed of the family : 70 km/h
<h3>Further explanation</h3>
Given
time = 2 hour
distance = 140 km
Required
The average speed
Solution
Distance is the length traveled by an object within a certain time
Average speed = total distance/total amount of time
Can be formulated :
Avg speed = d : t
Total distance traveled : 140 km
Total time : 2 hr
Avg speed = 140 : 2 = 70 km/h
A solid, but they are constantly vibrating
This is an example of sphere interaction of the biosphere, hydrosphere, and lithosphere.
