Answer:

There are 2.1 moles in $1.26 \times 10^{24}$ particles.

Step-by-step explanation:

Given : $1.26 \times 10^{24}$ particles

To find : Number of moles in given particle.

Solution : Since we know,

1 mole = $6\times 10^{23}$ particles.

So, 1 particle = $\frac{1}{6\times 10^{23}}$ moles

$1.26 \times 10^{24}\text{particle}=\frac{1.26 \times 10^{24}}{6\times 10^{23}}\text{moles}$

$1.26 \times 10^{24}\text{particle}=\frac{1.26 \times 10^{24-23}}{6}\text{moles}$

$1.26 \times 10^{24}\text{particle}=0.21\times 10\text{moles}$

$1.26 \times 10^{24}\text{particle}= 2.1\text{moles}$

Therefore, There are 2.1 moles in $1.26 \times 10^{24}$ particles.

A car travels for 4(t+3) hours at a constant speed of 10(t+3) km/h. If the total distance travelled by the car is 810 km, find t

IceJOKER [234]

Step-by-step explanation:

$\because \: time \times speed = distance \\ \therefore \: 4(t + 3) \times 10(t + 3) = 810 \\ \therefore \: 4(t + 3)^{2} = 81 \\ \therefore \: \{2(t + 3) \}^{2} = {9}^{2} \\ \therefore \: \{2(t + 3) \} = {9} \\ \therefore \: t + 3 = \frac{9}{2} \\ \therefore \: t = \frac{9}{2} - 3 \\ \therefore \: t = \frac{9 - 6}{2} \\ \therefore \: t = \frac{3}{2} \\ \therefore \: t = 1.5 \: hrs \\ speed \: of \: car = 10(t + 3) \\ \hspace{60 pt} = 10(1.5 + 3) \\ \hspace{60 pt}= 10 \times 4.5 \\ \red{ \boxed{ \bold{ \therefore \: speed \: of \: car = 45 \:km/ h}}} \\$
