What is the molarity of the solution with respect to NaCL

Chemistry
1 answer:
dezoksy [38]3 years ago
6 0
7.0 g in 220 ml corresponds to 7 x 1000/220 = 31.818g per 1000 cc of solution or 1 liter of solution

Molarity is moles per liter of solution by definition, so we need to know the number of moles of NaCl in 31.818 grams. The molar mass of NaCl is 58.5 grams(rounded off), so # moles = 31.818/58.5 = 0.543. 0.543 moles in a liter of solution defines the concentration as 0.543M

An ideal gas sample is confined to 3.0 L and kept at 27 °C. If the temperature is raised to 77 °C and the initial pressure was 1
Nadusha1986 [10]

The gas is confined in 3.0 L container ( rigid container) ⇒ the volume remains constant when the temperature is increased from from 27oC to 77oC and therefore V1=V2 .

Explain on any two materials that you would expect to use for the wheelchair (both back support and
Ugo [173]

Answer:

In the backrest use materials where it is easy to clean and where they do not absorb fluids, in this way it would be cooler, such as an ecological leather simulator.

And in the armrest as well, but in both areas we must not rule out that if or if it should have even a minimum of padded surface so that the patient or the person who spends most of the day in the wheelchair does not suffer from joint pain.

Explanation:

Some wheelchair factories also implement modern chairs where they are made of stainless steel structures lined with padded material with perforated fabrics that allow breathing and aeration of body areas that have contact with the fabric.
