Star converted every bit of its mass into energy conversion

Reference no: EM13657828

If a star converted every bit of its mass into energy the conversion efficiency would be 100%. But, the sun converts hydrogen into helium with an efficiency of only 0.7%. The sun has a, ass of 2X10^30kg. How long will the sun live if it changes all of its hydrogen to helium?
