Will 1 tube seal around a standard size bathtub?

Thank you for your question. We recommend using the 10.1 oz tube for your tub to be sure you have enough. One 10.1 ounce tube is enough to caulk two bathtubs and one sink. The squeeze tube is only 2.8 oz..

Is this low modulus silocone?

It worked well in my bathroom. My application does not require expansion. Think sink and shower.

Can this be used on a hairline crack in the bottom of a bathtub?

You shouldn't even be using that tub if it has a hair line crack. The tub needs to be replaced. I'm assuming that the tub in fiberglass. It has probably developed a hair line crack because it was not installed properly to begin with. The area beneath the tub should be filled with spray foam insulation to provide support for the tub. Some builders even use sand, though I would not recommend that. I speak from first hand experience. We had purchased a house that was about 15 years old. There was a shower and whirlpool in the master bath and a fiberglass tub in the hall bath. My husband gets up really early, so he would shower in the hall bath to avoid waking me. He a big guy, not obese by any means, just a big guy...about 200 lbs. He was shower one morning and the bottom of the tub just gave way and he was standing about 4 " lower. The builder hadn't put anything under the tub for support. I guess the tub had probably been used previously for bathing children. It was a mess! It this tub had been upstairs there would have been major damage and a much larger cost for repairs.
