Which direction does the decimal move from mega meters to meters
Temka [501]

To solve this problem, let us first understand what does mega meters mean. Now by definition, mega means a factor of one million which is a unit prefix in Metric Systems of units. It is denoted by the unit symbol M.

So for example if we have a mega of something, it means a million of something. So in this case, if we have 1 mega meter, what it means is 1 million meter, which is written as:

1 mega meter = 1,000,000 meter

 

To show the decimal points:

1.0 mega meter = 1,000,000.0 meter

 

So we see that the decimal point move 6 zeroes to the right, therefore the direction is to the right.

 

Answer:

<span>6 places to the right</span>

Perform the following mathematical operations and express the correct answer to the proper number of significant figures or deci
nordsb [41]

Answer: 7.71 + 4.31 + 1.7 + 4.00141= 17.72141

7.71 x 4.31 x 1.7 x 4.00141=  226.04433255

Explanation:

(i) 7.71 + 4.31 + 1.7 + 4.00141

= 7.71000+4.31000+1.70000+ 4.00141   [make like decimals]

= 17.72141    [By adding the corresponding places ]

(ii)  7.71 x 4.31 x 1.7 x 4.00141 =( 7.71 x 4.31) x 1.7 x 4.00141

= 33.2301 x 1.7 x 4.00141

= (33.2301 x 1.7) x 4.00141

=  56.49117 x 4.00141

= ( 56.49117 x 4.00141 )

=  226.04433255

Hence,  7.71 + 4.31 + 1.7 + 4.00141= 17.72141

7.71 x 4.31 x 1.7 x 4.00141=  226.04433255

1000 cm3 of hydrogen gas (hydrogen molecules, H2) contains x number of molecules at room temperature and pressure. Determine the
Gekata [30.6K]

Answer: Number of atoms in 500cm^3 of radon gas (radon atoms) at the same temperature and pressure is \frac{x}{2}

Explanation:

According to avogadro's law, volume of a gas is directly proportional to the number of moles present when temperature and pressure is constant.:

\frac{V_1}{n_1}=\frac{V_2}{n_2}

V_1 = Volume of the hydrogen gas = 1000cm^3

n_1 =  moles of hydrogen gas = \frac{xmolecules}{6.023\times 10^{23}molecules}

V_2=  Volume of the radon gas =500cm^3

n_1 =  moles of radon gas = ?

\frac{1000}{\frac{x}{6.023\times 10^{23}}}=\frac{500}{\frac{y}{6.023\times 10^{23}}}

y=\frac{x}{2}

Thus the number of atoms in 500cm^3 of radon gas (radon atoms) at the same temperature and pressure is \frac{x}{2}
