The taste of sour milk is lactic acid. What is the molecular formula for lactic acid if the percent composition is 40.00% C, 6.7
Svetradugi [14.3K]

Answer:

C3H6O3

Explanation:

To find the emperical of the compound,you divide the percentage composition of each element by it's molar mass(C=12, H=1, O=16).

For C,40/12=3.33. For H,6.71/1=6.71

For O,53.19/16=3.33.

Then divide everything by the smallest value which is 3.33

For C,3.33/3.33=1. For H,6.71/3.33=~2.

For O,3.33/3.33=1.

Emperical formula=CH2O

Molecular formula=(CH2O)n=90

(12+2*1+16)n=90

30n=90, n=3

molecular formula=(CH2O)3

molecular formula of lactic acid=C3H6O3.

lianna [129]

Answer:

saltation

Explanation:

  • Saltation is the transportation of particles by fluids such as by winds and water.  It takes place when loose matter is removed from the sea bed and gets carried by the fluid back to the surface.
  • Examples include pebbles, sand, and soil. Saltation layers can form during avalanches.

Why is very important to wait until the crucible is fully coleed to room temperature before weighting
Mars2501 [29]

If you do not wait until the crucible is at room temperature, its density will vary constantly until it reaches this temperature, since density is a property that varies with temperature. For the above reason, weighing a hot crucible will not allow the measurement of a constant weight on the balance, since <u>the weight of the object will be constantly changing, which will not allow a constant reading.</u>
