<u>Answer:</u> The volume of given amount O_2 at STP is 1.12 L

<u>Explanation:</u>

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Given mass of oxygen = 1.6 g

Molar mass of oxygen = 32 g/mol

Putting values in above equation, we get:

\text{Moles of oxygen}=\frac{1.6g}{32g/mol}=0.05mol

At STP:

1 mole of a gas occupies 22.4 liters of volume.

So, 0.05 moles of oxygen gas will occupy = \frac{22.4L}{1mol}\times 0.05mol=1.12L of volume.

Thus, the volume of given amount O_2 at STP is 1.12 L

the time t required to drive a certain distance varies inversely with the speed, r. if it takes 4 hours to drive the distance at
valina [46]
Hello,

Answer A

d :the distance in miles
t: the time in hours
v: the speed in miles/hours (vistesse)


d=v*t
==>d=40*4=160(mi)

d=55*x=160==>x=160/55=2.909090... (mi/(mi/h)=h)≈2.91(hours)

On babylonian tablet ybc 4652, a problem is given that translates to this equation: x x plus startfraction x over 7 endfraction
seraphim [82]

The correct option is (A). The solution of the equation is x=48.125.

Given an equation x+\frac{x}{7}+\frac{1}{11}\left(x+\frac{x}{7}\right)=60.

A statement that uses the equal sign to show that two expressions have the same value is called an equation. The equation is represented as ax+by=c.

Firstly, we will apply the distributive property to the given equation a×(b+c)=ab+ac, we get

x+\frac{x}{7}+\frac{x}{11}+\frac{x}{77}=60

Now, we will simplify the right-hand side equation by taking LCM, we get

\begin{aligned}\frac{77x+11x+7x+x}{77}&=60\\ \frac{96x}{77}&=60\end

Further, we will multiply both sides with 77, we get

77×(96x/77)=77×60

96x=4620

Then, we will divide both sides with 96, we get

96x/96=4620/96

x=48.125

Hence, the solution of the given equation x+\frac{x}{7}+\frac{x}{11}+\frac{x}{77}=60 is x=48.125.

Answer:

the width is 65

Step-by-step explanation:

width x length = area

w x 95 = 6,175

6,175 / 95 = 65

65 x 95 = 6175
