Explain why some people use the term decimal system as a synonym for the metric system?
Luda [366]

Answer:

The term Decimal is coined from the word Decimus. Decimus is a Latin word which means ‘tenth’.

The Decimal system is a system of numbering that is based on multiples of tens. It is flexible and easy to convert from one metric to another.

The preference of the term over the Metric System is because the word Metric is related more to the measurement of lengths if we looked at the origin of the word which is French.

Acetic acid (CH3CO2H) is the principal component in the vinegar. What is the molarity of an acetic acid solution if a titration
Alexxx [7]

Answer : The molarity of an acetic acid solution is, 0.0338 M

Explanation :

Formula used :

M_1V_1=M_2V_2

where,

M_1\text{ and }V_1 are the molarity and volume of acetic acid.

M_2\text{ and }V_2 are the molarity and volume of NaOH.

We are given:

M_1=?\\V_1=50.0mL\\M_2=0.0567M\\V_2=29.80mL

Putting values in above equation, we get:

M_1\times 50.0mL=0.0567M\times 29.80mL\\\\M_1=0.0338M

Hence, the molarity of an acetic acid solution is, 0.0338 M

0.00781 g = kg<br> helppppp
lapo4ka [179]

Answer:  The answer is:  " 7.81 kg " .

___________________________________________________

Explanation:

___________________________________________________

Note the exact conversion:   1000 g = 1 kg ;

0.00781 g = ? kg :

So:  To convert "0.0781 g" ; to "units in kg" ;

            →  we multiply the value:  0.00781 g ;  by "1000" ;

So:  Given:  " 0.00781 g " ;  

           →  we move the decimal point "3 (three) spaces forward" ;

   to get:  " 7.81 kg " .
