Convert 645 Newtons per quart to tons per liter. (The picture is a conversion table for help)
brilliants [131]

Answer:

0.067 ton/Litre.

Explanation:

645 Newtons per quart to tons per liter.

We'll begin by converting 645 Newton/quart to gram/quart (g/q). This can be obtained as:

1 N/q = 100 g/q

Therefore,

645 N/q = 645 N/q × 100 g/q / 1 N/q

645 N/q = 64500 g/q

Therefore, 645 Newton/quart is equivalent to 64500 grams per quart.

Next, we shall convert 64500 grams per quart to pounds per quart. This can be obtained as follow:

454 g/q = 1 pound/q

Therefore,

64500 g/q = 64500 g/q × 1 p/q / 454 g/p

64500 gram/quart = 142.07 pound/quart

Therefore, 64500 gram/quart is equivalent to 142.07 pound/quart.

Next, we shall convert 142.07 pound/quart to ton/quart. This can be obtained as follow:

2000 p/q = 1 ton/q

Therefore,

142.07 p/q = 142.07 pq × 1 ton/q / 2000 p/q

142.07 pound/quart = 0.071 ton/quart

Therefore, 142.07 pound/quart is equivalent to 0.071 ton/quart.

Finally, we shall convert 0.071 ton/quart to ton/litre. This can be obtained as follow:

1 ton/q = 1/1.06 ton/L

Therefore,

0.071 ton/q = 0.071 ton/q × 1/1.06 ton/L / 1 ton/q

0.071 ton/quart = 0.067 ton/Litre

Therefore, 0.071 ton/quart is 0.067 ton/Litre.

From the above illustration, 645 Newton/quart is equivalent to 0.067 ton/Litre.

A 1.11 g sample of caffeine, C8H10N4O2, burns in a constant-volume calorimeter that has a heat capacity of 7.85 kJ/K. The temper
VladimirAG [237]

Answer:

401135 kJ

Explanation:

From the balanced quation,

(q/n) = CΔE

Molar heat of combustion = 7.85kJk × (303.81-298.70)k

                                            = 7.85kj × 5.11

                                             = 40.1135kj

How does one Coulomb of charge compare with the charge of a single electron?
fgiga [73]
The charge of an e- is 1.60217657×10^-19 coulombs I.e. A very small number!
So 1 coulomb is much much bigger than the charge of an electron.
