I’m guessing you mean moles. So the big M stands for mol/L. That means first you’d want to convert your mL to L. To do this write your 250mL then make parenthesis for the conversion. 1L=1000mL
250mL(1L/1000mL). Since the mL is on the bottom in the parenthesis we can cancel them out. Now all we do is divide and keep the L.
.250L is what you get. Now we need to figure out how to cancel the L with what we have left. We know M stands for Moles/L so this means in order to get ride of L we need to multiply our new number times the 1.5
.250L X 1.5 moles
_______
1L
This gives us 0.375 moles NH4SO4
I believe the answer you're looking for is O=C=O !
The material of object. The size of object. The surface are of the object
We know that:
speed = distance / time
time = distance / speed
The speed of light is 3 x 10⁸ m/s
Now, we must convert the distance to meters to obtain our answer in seconds. After that, we will multiply it by 1000 to obtain the answer in milliseconds(ms)
1 mile = 5280 ft
2462 miles = 2462 x 5280 = 12999360 ft
1 ft = 12 inches
12999360 ft = 12999360 x 12 = 155992320 in
1 in = 2.54 cm
155992320 in = 155992320 x 2.54 = 396220492.8 cm
1 m = 100 cm
396220492.8/100 = 3962204.928 m
Time = 3962204.928 / 3 x 10⁸
= 0.0132 seconds
1 s = 1000 ms
0.0132 x 1000 = 13.2 ms
