Backpackers often use canisters of white gas to fuel a cooking stove's burner. If one canister contains 1.45 L of white gas, and
Vaselesa [24]

The number of  kilograms  of fuel   that are contained in one  canister  is 1.03 Kilograms


calculation

mass =  density x  volume

Density= 0.710 g/cm³

volume = 1.45 L

convert  1.45 l into cm³  to make the units  uniform

that is     1 L= 1000 cm³

              1.45 L=  cm³

by cross  multiplication

= (1.45 L  x 1000 cm³)  / 1 L  = 1450 cm³


mass is therefore =   0.710g/cm³  x 1450 cm³   =1029.5 grams


convert grams to Kg

1 kg = 1000 grams

  ? kg  =1029.5  grams

by cross  multiplication

= (1 kg  x 1029.5 grams) /1000 grams  = 1.0295 Kg ≅1.03 kg

Why can't 1−methylcyclohexanol be prepared from a carbonyl compound by reduction? select the single best answer?
forsale [732]
1−methylcyclohexanol is a tertiary alcohol. Tertiary Alcohols are synthesized by either reacting Ketone with Organometallic compounds like Grignard reagent or by hydration of substituted alkenes. <span>1−methylcyclohexanol can not be synthesized by reduction of carbonyl compound because it is not possible to have a starting carbonyl compound having carbonyl group along with three other alkyl groups (as carbon can only form 4 bonds).

Result:
           Tertiary alcohols don't contain a hydrogen atom at carbon attached to hydroxyl group that is why it is not possible to synthesize </span><span>1−methylcyclohexanol by reduction of carbonyl compound.</span>
