Elton is cooking. he measures vegetable oil using a measuring cup that has increments of 1 ounce. which of the following could be the volume of the vegetable oil with the correct number of significant digits? a. 1 ouncesb. 1.4 ouncesc. 1.41 ouncesd. 1.403 ounces

A. 1 ounces

Explanation:

Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.

Rules for significant figures:

Digits from 1 to 9 are always significant and have infinite number of significant figures. All non-zero numbers are always significant. For example: 654, 6.54 and 65.4 all have three significant figures. All zero’s between integers are always significant. For example: 5005, 5.005 and 50.05 all have four significant figures. All zero’s preceding the first integers are never significant. For example: 0.0078 has two significant figures. All zero’s after the decimal point are always significant. For example: 4.500, 45.00 and 450.0 all have four significant figures. All zeroes used solely for spacing the decimal point are not significant. For example : 8000 has one significant figure.

Since, the increments is of 1 ounce and which have only 1 significant digit. So, The volume of the vegetable oil which is measured must have only one significant digit.

Thus, answer is - A. 1 ounces

The correct answer is c
