Total distance divided by total elapsed time gives what quantity?
ki77a [65]
<h2>Total distance divided by total elapsed time gives : Average speed </h2>

Explanation:

Speed

It is the distance traveled by body with respect to time .

Its formula is Speed = distance /time

V=S/T

units : m/sec or Km/hr

Distance

It is total path traveled by body in any direction .

It unit and symbol is : S  and unit = m /Km

Average speed

It is the total distance traveled by body with respect to total time taken to travel that given distance .

Average speed = total distance /total time

A.s = T.D/T.T

unit = m/sec or Km/hr

Instantaneous velocity

It is the distance traveled by body at particular instant of time ,in given direction .

Displacement

It is the shortest path traveled by body in given direction .

How many grams of H2SO4 are needed to prepare 500. mL of a .250M solution?
zavuch27 [327]

Answer:

We need 12.26 grams H2SO4

Explanation:

Step 1: Data given

Volume of a H2SO4 solution = 500 mL = 0.500 L

Concentration of the H2SO4 solution = 0.250 M

Molar mass of H2SO4 = 98.08 g/mol

Step 2: Calculate moles H2SO4

Moles H2SO4 = concentration * volume

Moles H2SO4 = 0.250 M * 0.500 L

Moles H2SO4 = 0.125 moles

Step 3: Calculate mass of H2SO4

Mass of H2SO4 = moles * molar mass

Mass of H2SO4 = 0.125 moles * 98.08 g/mol

Mass of H2SO4 = 12.26 grams

We need 12.26 grams H2SO4
