Find the number of molecules in 27 grams of water

Chemistry
1 answer:
Aleks04 [339]3 years ago
5 0

In this question we have given the gram of water and we know that 1 mole of water = 18 gram of water and 27 g of water contain 1.5 g of water 27 / 18 = 1.5 g

As we know that avogandro'S no is equal 6.022*1023

1.5g * 6.022*1023 = 9.0 * 1023 molecules present in each 27 g of water.

I hope you will understand better now if you like then comment below and tell me. Best of luck.

The calcium ions released into the cytosol during excitation of skeletal muscle bind to
emmainna [20.7K]

Answer:

Bind to the protein complex troponin.

Explanation:

Excitation of skeletal muscle caused by the calcium ions. During excitation of skeletal muscle, after calcium ions released into the cytosol, they bind to the protein complex known as troponin and causing substitutions in the protein complex.

These alterations permit protein to push out from the myosin-binding sites on the actin filament.

Water (10 kg/s) at 1 bar pressure and 50 C is pumped isothermally to 10 bar. What is the pump work? (Use the steam tables.) -7.3
Andreyy89

Answer:

The pump work is 3451 kJ/s

Explanation:

Pump work (W) is calculated as

W = (h_f - h_i) \times \dot{m}

where

h_f is the enthalpy of water at its final state

h_i is the enthalpy of water at its initial state

\dot{m} = 10 kg/s is water mass flow

For liquids, properties are evaluated as saturated liquid. From the figure attached, it can be seen that

h_f = 762.81 kJ/kg

h_i = 417.46 kJ/kg

Replacing

W = (762.81 kJ/kg - 417.46 kJ/kg) \times 10 kg/s

W = 3451 kJ/s

What is the density of aluminum in pounds per cubic inch?
ASHA 777 [7]

Answer:

0.098 pounds per cubic inch

Explanation:

The density of aluminum is 2.7 grams per cubic centimeter (2.7g/cm^3)

2.7g/cm^3 × 1lb/453.59g × (2.54cm)^3/(1in)^3 = 0.098lb/in^3

You have two cups one is 6cm and other 10cm with no measurement and you have to pour 8cm of water into the 10cm cup using the tw
Korolek [52]

Here’s one way to do it.

1. Fill the 6 cm cup.

2. Pour its contents into the 10 cm cup. This leaves 4 cm yet to be filled.

3. Refill the 6 cm cup and use it to fill the 10 cm cup. This leaves 2 cm in the 6 cm cup.

4. Empty the 10 cm cup and add the 2 cm from the 6 cm cup.

5. Refill the 6 cm cup.

6. Pour its contents into the 10 cm cup.

The 10 cm cup now contains 8 cm of water.
